Intrinsic charm and photon-gluon fusion contributions to muoproduction of charm

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The charm muoproduction data has been analysed in terms of the intrinsic charm and the γG fusion contributions, in order to estimate the intrinsic charm content of the nucleon. Unfortunately the result is sensitive to the choices of fragmentation function and the energy scale of αs, that one makes for the fusion contribution. Nonetheless, there is one solution with a hard intrinsic charm spectrum—very similar to that suggested by the recent hadroproduction data.
